Remove unused 'mut'
Fixes compilation for me, previously I got:
rror: variable does not need to be mutable
--> tokio-xmpp/src/xmpp_stream.rs:92:58
|
92 | #[cfg_attr(rustc_least_1_48, allow(unused_mut))] mut self: Pin<&mut Self>,
| ----^^^^
| |
| help: remove this mut
|
note: the lint level is defined here
--> tokio-xmpp/src/lib.rs:3:22
|
3 | #![deny(unsafe_code, unused, missing_docs, bare_trait_objects)]
| ^^^^^^
= note: #[deny(unused_mut)] implied by #[deny(unused)]
